Applet java rodando em apache

olá colegas,

estou ocm o seguinte problema:

preciso de um chat java que rode via applet num servidor apache.

fiz um applet com sockets, o mesmo do livro "use a cabeça".

porém não roda o applet na web devido a restrições dos applets.
preciso de alguma adaptação ou outra sugestão de como fazer isto.

segue o cliente:

public class Cliente extends JApplet implements Runnable {

/** Initializes the applet Cliente */
    public void init() {
        try {
            java.awt.EventQueue.invokeAndWait(new Runnable() {
                public void run() {
                    initComponents();
                    setUpNetworking();
                     Thread readerThread = new Thread(new IncomingReader());
                     readerThread.start();

}
         
            });
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
   
                       
    private void initComponents() {

jPanel1 = new javax.swing.JPanel();
        jScrollPane1 = new javax.swing.JScrollPane();
        conversa = new javax.swing.JTextArea();
        jScrollPane2 = new javax.swing.JScrollPane();
        enviar = new javax.swing.JTextArea();
        brEnviar = new javax.swing.JButton();

jPanel1.setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());

conversa.setColumns(20);
        conversa.setEditable(false);
        conversa.setLineWrap(true);
        conversa.setRows(5);
        conversa.setWrapStyleWord(true);
        jScrollPane1.setViewportView(conversa);

enviar.setColumns(20);
        enviar.setLineWrap(true);
        enviar.setRows(5);
        enviar.setWrapStyleWord(true);
        jScrollPane2.setViewportView(enviar);

brEnviar.setText("enviar");
        brEnviar.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                brEnviarActionPerformed(evt);
            }
        });

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());

          try {
               // System.out.println(enviar.getText());

}

public void run() {

    }

public class IncomingReader implements Runnable{

}

} catch (Exception e) {

}

private void setUpNetworking(){
        try {

            InputStreamReader streamReader = new InputStreamReader(sock.getInputStream());
            reader = new BufferedReader(streamReader);

}

private javax.swing.JButton brEnviar;

    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JScrollPane jScrollPane2;

BufferedReader reader;
    PrintWriter writer;
    Socket sock;

}

agora a classe servidor:

public class VerySimpleChatServer implements Runnable{

ArrayList clienteOutputStreams;

public void run() {
        go();
    }

public class ClienteHandler implements Runnable{

BufferedReader reader;
        Socket sock;

public ClienteHandler(Socket clientsocket){

sock = clientsocket;

try {
                InputStreamReader isReader;
                isReader = new InputStreamReader(sock.getInputStream());
                reader = new BufferedReader(isReader);

} catch (IOException ex) {
                System.out.println("erro no ClientHandler " + ex);
            }

}

public void run() {
           String message;

try {
                while ((message = reader.readLine()) != null) {

System.out.println("lendo no servidor "+ message);
                    tellEveryone(message);
                }

} catch (Exception e) {
            }
        }

}

public static void main(String[] args) {

new VerySimpleChatServer().go();
    }

public void go(){
        clienteOutputStreams = new ArrayList();

try {

ServerSocket serverSocket = new ServerSocket(5000);
            while(true){
                
                Socket clientSocket = serverSocket.accept();
                PrintWriter writer = new PrintWriter(clientSocket.getOutputStream());
                clienteOutputStreams.add(writer);
                Thread t = new Thread(new ClienteHandler(clientSocket));
                t.start();
                System.out.println("conectando");
            }

} catch (Exception ex) {
            System.out.println("erro no metodo go "+ ex);
        }

}

public void tellEveryone(String message){
        Iterator it = clienteOutputStreams.iterator();

while (it.hasNext()) {

try {

PrintWriter writer = (PrintWriter) it.next();
                writer.println(message);
                writer.flush();

} catch (Exception e) {
                System.out.println("erro no tellEveryone "+ e);

}

pela ferramente netbeans executando primeiro o servidor, e depois o cliente (ou os clientes roda bonitinho).
ja no browser não.

obrigado
